N2 - A pattern-reconfigurable antenna based on a simple single-element microstrip antenna is presented. The antenna has a shorting wall near the patch center to introduce two slightly shifted resonances at its two radiating edges. A stub-loaded varactor is mounted at one of the patch radiating edges to obtain pattern reconfigurability, by electronically detuning the frequency of one of the resonances. Preliminary measurements of a prototype demonstrate that the antenna exhibits beam squint up to 39° on one side of the patch at the center frequency of 2.40 GHz, when the bias voltage is tuned from 18 to 3.8 V. Also for a fixed bias voltage of 6.3 V, the beam can scan from 8 ° to 43 ° as a function of frequency within the operation bandwidth from 2.35 to 2.45 GHz. The presented results validate the concept which will be further extended to scan beam on two sides with frequency selectivity.
